APPLICATION OF UNCERTAIN VARIABLES TO STABILITY ANALYSIS AND STABILIZATION FOR ATM ABR CONGESTION CONTROL SYSTEMS

摘要

The paper presents the application of uncertain variables to stabilization for ATM ABR congestion control systems. The time-varying system with unknown parameters is considered. The unknown parameter is assumed to be a value of uncertain variable described by the certainty distribution given by an expert. The estimation of the certainty index that the system is stable is presented. The estimation consists in the determination of the lower and upper bounds for the certainty index via the determination of sufficient and necessary stability conditions. A specific stabilization problem is considered.
